OPERATING BOLTS AND I'JQMZKS` FOR` CONTROLLING- SERIES OF DOORS.

`Spt-:ciicaton of Letters Patent No. 11,093, dated June 13, 1854.

To all wimmzt may concern Be it kno-wn tha-tI, DAVID J. STAGG, of Hoboken, New Jersey, have invented a new and useful Improvement in Bolts and Locks for Controlling a Plurality of Doors wit-h One Key, Especially Intended for Prisons, but Applicable to other Buildings, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making partv of this specification, in which-f Figure l, is an eleva-tion of a wall with several doors; Figs. 2 and 3 sections taken at the lines A, a, and B, b, of Fig. 1; and Fig. 4i a perspective view of the hasp C.

j `My invention consists in employing on each of any desired number of doors, locks having double thro-w or double acting bolts in combination with hasps attached each to one of a system of sliding bars or bolts op erated simultaneously and controlled by one lock, the said hasps being provided with j `a projecting lip o-n a part of the length, so

that when the bolts of the several locks are only thrown out once, the sliding of the system of hasps will lock and unlock all the doors, and when the lock bolts of any of the doors are thrown out to the full extent ot their capacity, then such doors will not be unlocked by the operation of the sliding hasps. By this means any desired number of the doo-rs can be simultaneously locked or unlocked, while the others will remain locked and under the control each of its separate lock bolt.

In the accompanying drawings a, represents the wall of the building, and the doors leading to the series of cells. There is a vertical bar o, which can be moved up and down by means of a hand lever d, jointed thereto, and this bar is connected by means of an angle lever (e) toa horizontal bar f, extending along and above the range of doors, so that this bar can be moved back and forth by the vertical bar. And to the horizontal bar f, are jointed by angle levers g, a series of vertical bolts la, located near the edge of the doors. These bolts L should beV so connected with the horizontal bar f, by the angle levers as to balance or nearly balance each otherandthe vertical bar c, to facilitate themovement of the whole series. j

The ends of the bolts can be fitted tol` slide in suitable holes in plates of metal z, secured -of rivets or screw bolts 70,

in the wall. And the doors provided with hasps j, passing through the plates e', so that when the doors are closed, the bolts will, when let down, pass into and secure the hasps and thus bolt the doors. And the vertical bar c, is provided with a spur la, project-ing from one edge, so that when the bar is forced up to throw all the bolts through the hasps, the bolt Z, of a lock m, can be thrown under the spur 7c, to lock the whole series of bolts. In this way all the doors can be bolted and locked simultaneously, and vice versa. But as it is important, in prisons and other like buildings, to have some doors'remain closed `when the others are opened, I secure, near' the opening edge of the doors, a plate of iron n, with a groove in which the b oltl slides, and to the bolt I secure a hasp 0, by means j that work in a slot in the plate a, so that the hasp will slide up and down on the plate n, as the series of bolts are operated. That edge of the hasp o, which is toward the door is provided with a projecting lip g, occupying the lower half of its length, the upper half being wit-hout.

The lock 1', on the doors is provided with a double acting bolt s, well known to lock makers, that is: a bolt which operates as a spring latch bolt, but which, when thrown out by the key no longer acts as a spring bolt. When any particular door is desired to be kept locked whenthe others are opened, the bolt of the lock must be thrown o-ut by the key, so that the hasp in any position will extend over the lock bolt, and keep the door locked, and when it is desired to have the door so that it will be unlocked with all the rest, then the lock bolt must be in the position in which it acts asa spring lock bolt, for in thatnposition, when the hasp is let do-wn the projecting lip g, will be below the lock bolt and liberate it, and when the hasp is drawn up with the system ot bolts, the lip slides over the lock bolt, and secures the door.

The position of theprojecting lip g, on the hasp, must depend upc-n the bolt to which it is attached, for some move up while others move down, and I have described it above as applied to a bolt which moves `up in securing the doors. 1

I have not given any description of the inode of concealing the several bars, bolts doors in elevation, either the one set of bolts can be elongated and extended up to the upper range or ranges as represented at t, t; ,or the same arrangement may be repeated for each range of doors as repre- 10 sented at u, and o.

l claim- In combination With double throw lock bolts or double acting lock bolts, `Von the doors, substantially as specified, the sliding hasps constructed substantially as specified, and attached to and operated by the System of bolts as set forth.
